Acuity Index v0.9.1 Released

Ecosystem
1

Acuity Index is an open source Substrate event indexer. It helps dapps consume event data through a real-time indexing API.

Since v0.8, we shipped config-driven index specs, explicit query keys, hot reload, reindexing across spec changes, composite/multi-field keys, Prometheus metrics, event proofs, JSON-RPC 2.0, better throughput/reliability, and stronger production safety. v0.9.1 adds simpler subscriptions, cleaner event payloads, top-level timestamps and WS heartbeats.

As far as I understand, Acuity Index is a client that reads runtime events via subxt and indexes them for fast querying. It also pins the indexed data to IPFS, along with an embedded key-value database and a finality prover for events.

As a result, frontend applications that submit extrinsics can query indexed events instead of directly querying on-chain state.

Can you confirm it?
